I don't know any places in Columbus. But what you're looking for is an appetizing store, not a deli. A deli sells meat, an appetizing store sells fish and dairy. I don't know if that will help you find a store, but if you search for the right thing it might help a little.

Costco if there is one in Columbus. But it will be in huge containers.

PS Never heard the term appetizing used as a type of store except from my (Brooklyn NY born) husband. I assumed he was making a mistake when I first heard him say it. He also calls ground beef "chop meat" and calls shopping carts "wagons."

I speak using the same words as your husband. I was born and raised in Connecticut, father from Brooklyn, mother and siblings from the Bronx.To this day I am accused of having a NY accent, or being from NY.In New Haven, the last of the kosher appetizing stores morphed into a kosher deli that sold bith meat and dairy in the mid 1960s. Out of town, it is/was (when there were kosher delis) common to have both meat and dairy in a kosher deli at separate counters. BUT a city with 35000Jews went from 10 kosher delis to none by 2005. Instead, the major suoermarkets carry the Hebrew National line and have dedicated kosher slicers, packaged smoked fish and in stire bakeries under kosher supervision. The independent kosher deli can not survive.

The packaged smoked whitefish salad (Acme) is availabel in major supermarkets throughout New England.

Back in the day sable wouldn't have been availabel at a kosher appetizing store, only in a place such as Russ and daughters which catered to Jews but wasn't kosher.

BTW>>>my grandmother always made chop meat (neck and skirt) for hamburgers. She made it in a wooden bowl with a hochmesser. Chop meat is what my parents and I call ground beef, but originally it wasn't put through a grinder.

back in the 50s and 60s (and even earlier) there were multiple fishes sold in the American marketplace as sable. Not all were kosher. The kosher appetizing stores avoided the problem by not carrying sable at all.In those days, the delis and butchers might have a Hechsher from a local rabbi with a card in the window, but appetizing usually was just sold under the 'good name' of the proprietor.

Thinking about the appetizing stores in NYC, Barney Greengrass, Russ & Daughters, Murray's, etc... i think that's still the case. With the difference being most Orthodox Jews will no longer trust just the "good name".

Russ and Daughters was never a kosher establishment. In fact Mr. Russ split with his original partner/brother-in-law IIRC because partner wanted sabbath observance and no non-kosher fish sold..................
